- Detail-oriented individual with strong analytical and organizational skills

how can i improve this?

I am afraid I don't understand your question. You want to improve your skills and need to take courses or you just want to write your summary?

Well I would list some of those extracurricular activites. I think you need to express how you obtained those skills. Is this what you currently use on your resume?
